Curing material for household garbage leachate membrane concentrated solution and evaporation mother solution and application of curing material
The invention provides a curing material for a household garbage leachate membrane concentrated solution and an evaporation mother solution, and belongs to the technical field of household garbage leachate full-quantitative treatment. The curing material is composed of a curing component and an additive, wherein the additive is prepared from polyacrylic acid, pregelatinized starch, light calcined magnesia, tetracalcium sulphoaluminate and polyaluminum ferric chloride according to a certain proportion. The additive provided by the invention can solve the problems of slurry bleeding and delayed coagulation of cement or cement and lime and other curing materials during curing of a membrane concentrated solution and evaporation of a mother solution, and meets the requirement of timely transition and landfill of a cured body. The additive provided by the invention not only can improve the treatment efficiency of a membrane concentrated solution and an evaporation mother solution, but also can reduce the use of curing materials such as cement lime by 20-30% while achieving the primary effects of no bleeding and rapid setting and hardening of slurry, and has better environmental protection and economic benefits.
本发明提供了一种生活垃圾渗滤液膜浓缩液及蒸发母液用固化材料，属于生活垃圾渗滤液全量化处理技术领域。本发明所述固化材料由固化组分及添加剂组成，其中添加剂是由聚丙烯酸、预糊化淀粉、轻烧氧化镁、硫铝酸四钙和聚氯化铝铁按一定比例制备而成。本发明的添加剂能够解决水泥或水泥加石灰等固化材料在固化膜浓缩液及蒸发母液时出现的浆体泌水和缓凝问题，达到固化体及时转场填埋的要求。本发明的添加剂不仅能够提高膜浓缩液及蒸发母液处理效率，在达到浆体不泌水且快速凝结硬化的首要效果时还能减少20％‑30％水泥石灰等固化材料的使用，具有较好的环保和经济效益。
